Eulerroom Equinox: Live Code Performance

I had the great pleasure to perform as part of the Eulerroom Equinox live coding event yesterday. It has been an amazing four days of live code streams from around the world and I’m grateful to the organizers for their incredible work putting this all together. Bravo to everyone and thanks to all of the incredible performers and presenters, very inspiring!

Additive Pitch Rhythms Using Hexbeat

Practice session today using additive pitch hexbeat rhythms to generate melodic contours.

Each hexbeat() is generating sequences of 1’s and 0’s which are then multiplied to alternate between things like 7 and 0.  So if I add one that alternates between 2 and 0, I get 9,7,2, and 0 as possibilities.  Then with say 4 and 0, I get additional combinations.  With the patterns of different lengths (I’ve been using mostly prime number lengths) it generates a nice long overall pitch pattern, which is then masked by the rhythmic hexplay() pattern.  I then add a choose() to say “play 70% of the time” and I find all of that together is quick to write, generates good variety, but has an underlying structure that is stable.  (It’s been on my mind how to mix randomness + stability in interesting ways and I’ve found these explorations have been leading to some interesting pattern generation.)
